This study aims to find out the soil morphology diversity at the southern flank of Mt.Merapi Yogyakarta, Indonesia. The field research was conducted using purposive sampling method where each site of geomorphological unit as representing of the cone, upper, middle and lower slopes of Mt.Merapi. Poligenesis of the soil morphology was observed at pedon P1 with composition of the upper and buried soil was Typic Hapludands-Typic Hapludands, P3 (Andic Eutrudepts-Vitrandic Udorthents), P4 (Vitrandic Udorthents -Typic Hapludands), and P5 (Andic Eutrudepts-Andic Eutrudepts). Whereas the monogenesis of the soil morphology was observed at pedon P2, P6, P7 and P8 with subgroups of Typic hapludands, Andic Eutrudepts, Andic Dystrodepts and Typic Udorthents, respectively. Soil morphogenesis diversity (polygenesis) shown by the presence of a pedon having more than one soil profile was not a limiting factor for crop roots growth, so the agro-ecosystem recovery process was relatively fast.
Outdoor research was conducted in the coastal region of Parangtritis from December 2015 up to April 2016, with the purpose is to determine the soil characteristic of coastal land of Parangtritis and its suitability for soybean cultivation. This research was conducted using the observation method by collecting primary and secondary data. Primary data were soil characteristics which determined using the laboratory analysis procedures, while secondary data were supporting information obtained from local government agencies. The results showed that the coastal land of Parangtritis had a sandy texture, very fast soil drainage, the effective depth of low to moderate soils, low salinity, low cation exchange capacity, percentage saturation of medium to high bases. Based on the results of the analysis of primary and secondary data, actually the sandy land of Parangtritis is categorized into land suitability class S3r-1; r-2 for soybean plants, with soil drainage and texture as a limiting factor. Potentially, to reduce the negative effects of existing limiting factors, the addition of large amounts of organic matter, in-organic amendments, and NPK fertilizer is highly recommended.
Lack of information concerning the conversion rate of agricultural to non-agricultural land in the last decade has become an important issue in Sleman Regency. The aim of this study was to determine the changes in land use and the land conversion rates in five years for three periods of 1990-1995, 2000-2005, and 2010-2015. The study was conducted using descriptive methods which were analyzed spatially using Landsat imagery of 1990, 1995, 2000, 2005, 2010, and 2015. Identification of the land conversion rate covered 17 districts by comparing the land use classification data. The results showed that land use in Sleman Regency cover paddy fields, moorlands, yards, forests, barren land, and other land uses. The highest rate of land conversion occurs in groundwater bodies, paddy fields, and plantation area in different periods. The highest rate of land conversion in Sleman Regency in period 1 (1990-1995) was in paddy fields, which was 8,953.04 ha or 1,790.61 ha/year. In period 2 (2000-2005), the highest land conversion rate was in groundwater bodies, which was 3,471.44 ha or 694.29 ha/year. Meanwhile, in period 3 (2010-2015), the highest land conversion rate was in plantation areas, which was 7,767.33 ha or 1,553.47 ha/year.
Perkembangan kota sering menggeser keberadaan ruang publik, sehingga kuantitas dan kualitas ruang terbuka khususnya Ruang Terbuka Hijau (RTH) saat ini mengalami penurunan yang sangat signifikan dan mengakibatkan penurunan kualitas lingkungan hidup perkotaan yang berdampak ke berbagai sendi kehidupan perkotaan antara lain sering terjadinya banjir, peningkatan pencemaran udara, dan menurunnya produktivitas masyarakat akibat terbatasnya ruang yang tersedia untuk interaksi sosial (Peraturan Menteri Pekerjaan Umum, 2010).Secara sistem, RTH kota berfungsi menunjang keamanan, kesejahteraan, peningkatan kualitas lingkungan dan pelestarian alam. RTH kota pada umumnya terdiri dari ruang pergerakan linear atau koridor dan ruang pulau atau oasis (
Sampah merupakan permasalahan klasik yang belum terpecahkan dengan baik. Kesadaran masyarakat terhadap pengelolaan sampah masih rendah, termasuk dalam pengelolaan sampah organik. Daerah perkotaan, umumnya menjadi penyumbang sampah terbesar. Studi ini dilakukan untuk mengetahui tingkat pengetahuan masyarakat Kotagede terhadap pengelolaan sampah organik. Sasaran studi adalah anggota Muhammadiyah di lingkup PCM Kotagede. Metode studi yang digunakan adalah metode survei. Pelaksanaan survei dilakukan sebelum dan setelah dilaksanakan penyuluhan tentang peningkatan nilai ekonomi sampah organik. Survei dilakukan terhadap 55 orang peserta penyuluhan Upaya Peningkatan Nilai Ekonomi Sampah Organik. Hasil survei sebelum dilaksanakannya penyuluhan, 100% peserta mengetahui bahwa sampah organik dapat diolah kembali. Dari proses pengolahan sampah tersebut terdapat 23 orang (42%) responden paham tentang pengolahan sampah. Setelah penyuluhan dilaksanakan, sebanyak 84% paham tentang proses pengolahan sampah, sedangkan 16% belum memahami. Dari hasil tersebut, semua peserta menghendaki dilakukannya pengelolaan sampah organik yaitu dengan praktek pembuatan pupuk organik.Increasing Knowledge of the Kotagede CommunityIn Organic Waste ManagementABSTRACTGarbage is a classic problem that has not been resolved properly. Public awareness of waste management is still low, including in organic waste management. Urban areas are generally the largest contributor to waste. This study was conducted to determine the level of knowledge of the Kotagede community on organic waste management. The target of the study is Muhammadiyah members within the PCM Kotagede. The study method used was a survey method. The survey was carried out before and after counseling on the increase in the economic value of organic waste. The survey was conducted on 55 participants of counseling on Efforts to Increase the Economic Value of Organic Waste. From the survey results before the implementation of counseling, 100% of the participants knew that organic waste could be recycled. From the waste processing process, 23 people (42%) of respondents understand about waste processing. After counseling was carried out, as many as 84% understood about the waste processing process, while 16% did not understand. From these results, all participants wanted organic waste management to be carried out by practicing organic fertilizer production. Keywords: Economic; compost; MPM Kotagede; Garbage
